Customer Reviews

5 in. x 25 ft. Insulated Flexible Duct R6 Silver Jacket is rated 3.9 out of 5 by 14.
Rated 5 out of 5 by from Works Awesome as a portable A/C exhaust hose! 14,000 btu portable mini heat pump came with a uninsulated plastic exhaust hose that released a massive ammount of heat. Instead of wrapping it with insulation, which was going to cost about the same ammount, I tryed this hose and it is a night and day difference. I imagine this is saving me a ton of money too in energy costs as now my a/c unit shuts off when reaching set temperature, where as before, it was just constantly running trying. Since it is made out of plastic and aluminum and it is I side not being moved around alot, I think this hose will last a long time. Now if you are moving it around, have crazy animals or children, that can be another story ;)

Rated 4 out of 5 by from As advertised This seems like a well-made product. I bought it to replace the uninsulated exhaust duct that came with a Delonghi roll-around air conditioner -- a plastic hose that heated the room on the way to the window vent. Now the system is much more efficient. But watch out: the five-inch diameter is unusual, and at first Home Depot shipped me a four-inch duct by mistake.

Rated 2 out of 5 by from Not quite as described Ultimately, this is a 5" diameter flexible duct wrapped in insulation. However, the flexible duct portion is unusually soft and is prone to being pinched or squished if bent at too severe of an angle, unlike other flexible ducts I've used before. Also, the photo shows a tightly wrapped duct with the insulation adding just a few inches around, while the actual product has nearly a full foot in diameter because of the loosely wrapped insulation. It took quite a bit of maneuvering and duct tape to get this thing down to a size that fit where we needed it.

Rated 1 out of 5 by from cheap cheap cheap This was installed in my house by someone cutting corners and luckily I noticed it was ripped in several sections before drywall covered it up! I will be replacing this with aluminium flexible duct. The thin plastic is going to degrade over time and I don't want to risk it with duct work dry-walled into the floor joists. I also thought it was odd that the insulation was much larger than the 5 inch duct.
